Tooth decay can occur when the baby is put to bed with a bottle, or when a bottle is used as a pacifier for a fussy baby. If your infant or toddler does not receive an adequate amount of fluoride, they may also have an increased risk for tooth decay. The good news is that decay is preventable by keeping a few things in mind. By consulting the dentist, he can guide you the right way. Proper cleaning of teeth after feeds, not feeding at bedtime or giving clean pacifiers not dipped in sugary fluids like honey all help prevent baby bottle decay.
